ETED 1" P TE SUBSOILER- ATTACHMENT FOR FLOWS.

Application filed December 6, 1920. Serial No. 428,588.

To all whom-it may concern:

Be it known that I, FRANK'NL DYKE, a citizen of. the United States,residing at Ramona, in the county of San Diego and State of California,have invented certain new and'useful Subsoiler Attachments for LPIOWS,ofwhich the following is a specification.

My invention relates to an attachment for plows for breaking the groundin the furrow behind the plow to serve as a subsoiler and the objects ofmy invention are: first,

to. provide an attachment which is applicable for and may be readilyapplied to any plow now inuse for breaking the ground below the sole ofthe plow; second, to provide an attachment of this class which is adustable so that it may be regulated for different depths; third, toprovide an attachment of this class which is positioned so that it isout of the way when in use with any kind of a plow; fourth, to providean attachment of this class which is easy to install and fifth, toprovide an attachment of this class which 7 is very simple andeconomical of:c0nStruc tion, durable, easy to operate, adjustablethroughout and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter .myinvention consists of certain novel features of construe tion,combination and arrangement of parts and portions as will be-hereinafterdescribed in detail and particularly set forth in the appended claims,reference being had to the accompanying drawings and to the charactersof reference thereon which form a part of this application in which:

Figure 1 is a side elevational view of an ordinary wooden beam walkingplow showing portions broken away to facilitate the illustration andshowing my attachment positioned thereon ready for use; Fig. 2 is anenlarged fragmentary detailed view of the upper end of the main verticalsupporting member; Fig. 3 is an enlarged detailed view of the clamp andclevis members for supporting the beam of the attachment on the plow;Fig. 4 is a sectional view through 4-4 of Fig. 1, on an enlarged scale;Fig. 5 is a view similar to that of Fig. 1, showing the attachment inconnection with a steel beam walking plow, the position of theattachment being slightly modified from that of Fig. 1.

. Similar characters of reference refer to similar parts and portionsthroughout the several views of the drawings.

The attachment shoe 1, beam 2, U bolt member 3, clip 4, clevis 5, frontend support 6, clip 7 and spring 8 constitute the principal parts andportions of my attachment The shoe member 1 may be of any kind orcharacter for the purpose of breaking up the ground in the furrow belowthe sole of the plow and is secured to the beam 2. This beam 2 ispreferably a metallic beam about two and onehalf by five-eighths-of aninch in cross section, shaped as shown best in Figs. 1 and 5 of thedrawings. It is provided intermediate its ends with a plurality ofspaced holes 2 which are adapted for the reception of bolt 5 oftheclevis 5. This clevis 5 is pivotally mounted in a hole in the lug 4which extends upwardly on the clip member 4. The main portion of thisclip provided nuts 3, thus providing means for securing the clamp,consisting of the U bolt 3 and clip 4 securely on the member A and theclevis being pivotally mounted therein permits the slight shiftingmovementof the beam relctively to the member 4 and the plurality ofholes in the beam provides for adjustment of the beam 2 on the member 4.The front end of the beam is provided with a plurality of holes 2 overwhich is pivotally mounted the bifurcated end of the supporting member 6which is also provided with a plurality of holes 6 thus providing forthe vertical and longitudinal adjustment of the end of the beam, the twobeing held in their relative position by means of a bolt 6 The upper endof this supporting member 6 is shiftably mounted in a clip member 7secured on the side of the beam of the plow as shown best in Fig. 1 oron the brace between the handle and the beam as shown in Fig. 5. Thisclip member 7 is provided with teeth 7 a adapted for the teeth 6 on themember 6 and mounted on the opposite side of the member 6 from the teeth6 is a spring 8 adapted to hold the teeth in engagement with the teeth 7on the clip 7, it being here noted that the pressure is ordinarilyclownward on the front end of the beam 2 when in use and at the clevisit is upwardly. The upper end of this supporting member 6 is purview ofmy invent-ion; the; constructiorn, combinatlon and arrangementsubstantially as set-forth: in the appended claims.

It is obvious that with thisconstruction, there. is provided anattachment which'maybe used with plows of dillerent kindsand' characterfor. breaking; up the groundbehmd'the plow in the turrow belowthe S01v1ofthe plow; that the attachment is so 0011?- structed that it may be,adjusted: for: di'fiv ferent depths that it may 'be clamped to thesupport A in the-r positions desired for. the;

best results by: securing the-clamp formed. by the J bolt 3-andelip ltosaid support A. and the clev-is will hold theheam from raising" but willpermit-i slight movement; and'that the frontendofithe-heam isrigidlysupported so tllitti it may be adj uste'd forrregulating thedepth oh the plow.
